MADISON, Wis. (AP) -- The Wisconsin Assembly has passed a Republican bill that would strip most public workers of their collective bargaining rights.

Minority Democrats stalled the vote by launching a filibuster and offering dozens of amendments, forcing Republicans to defeat each proposal one-by one in a session that stretched on for more than three days straight.

The bill now goes to the Senate. Republicans control that house, too, but it's unclear when a vote may come. Senate Democrats have fled the state to prevent a vote.

Tens of thousands of protesters have converged on the state Capitol for days to demonstrate against the bill. They cheered outside the Assembly during the debate's daylight hours and retreated to makeshift sleeping camps in the Capitol rotunda overnight.
